This is true once #BBM brings on voice and video for iOS and Android there would be no need for any other messaging app. BBM will be the first messaging app that has all features combined in one (Funny that blackberry devices already enjoy this feature but it is not proving to be a strong selling point for the device as everyone by now know the BB situation; probably apps are more important)

However what scares me, is WHEN will #BBM bring voice and video to iOS and Android? Because if VIber or Whatsapp bring those featues onboard before #BBM then we're screwed people will stick to them as they are more familiar and got used to them.
BlackBerry needs to step up their game for once and push those features asap!!!!

Just did on my Q10 from T-Mobile running on 10.2.1.575 now i can make and receive calls but i can't hear the other person when i call and he picks up. And when he calls even though I answer it keeps ringing on his end as if I never picked up. So hope someone else had better luck with this versionm
